JOHN P. ONDERDONK, OF PHILADELPHIA, PENNSYLVANIA.

METHOD OF MAKING PAPER BAGS.

SPECIFICATION forming part of Letters Patent No. 318,016 dated May 19,1885.

Application filed December 4,1883.

To all whom, it may concern:

Be it known that I, J OHN P. ONDERDONK, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented a new and useful Improvement in the Methodof Making Paper Bags, of which the following is a specification.

My invention relates to an improved method of making paper bags havinginward bellows-folds and a satchel-bottom, which paper bags were fullyshown and described in my application filed May 26, 1883. I attain thisby the method illustrated in the accompanying drawings, in which Figure1 represents an ordinary paper tube in'which two slits or separations, AA, are cut. Fig. 2'represents the paper tube folded in a rectangularform. Fig. 3 represents the tube folded with inward bellows-folds. Fig.4 rep resents the manner in which the bottom is then folded. Fig. 5shows the manner in which the flaps D D are then folded and pasted. Fig.6 shows the completed bag. Fig. 7 represents the bag open for use. Fig.8 represents the bottom folded as in Fig. 4. Fig. 9 represents thepieces F and G folded one upon the other and pasted together. Fig. 10shows the flaps D D folded over upon and pasted to the pieces F and G.Fig. 11 represents the bag open for use.

In Fig. 1, which represents an ordinary paper tube, B, two slits, AA,are cut. The tube is then opened out, as represented in Fig. 2. Thetube is then folded with inward bellowsfolds, as represented in Fig. 3.The tube may be slit, as shown in Fig. l, or the corners may be cutapart after the tube is folded with inward bellows-folds, as shown inFig. 3. Fig. 4 represents the manner in which the bottom of the tube isthen folded, making the triangular piecesG G and the flaps D D. Paste isthen applied along the dark lines E. The flaps D D are then folded overupon the triangular (No model.)

The bag appears as in Fig. 6, and when open for use appears as in Fig.7.

Similar letters refer to similar parts throughout the several views.

The pieces F and G may be folded down first and pasted together, asshown in Fig. 9, and the flaps D D being supplied with paste, as shownby the dark lines in Fig. 8, are then turned over upon the pieces F andG and pasted to them, as shown in Fig. 10. The bag open for use appearsas in Fig. 11.

The flaps D D may be of any length desired. They may be partially cutoff or turned over their whole length, as shown in the drawings.

The object of my invention is to make a bellows-fold bag having asatchel-bottom which is easily manufactured and is not subject to theobjections of paper bags having bellowsfolds and satchel-bottoms inwhich the corners are not cut apart as in my invention.

Having thus fully described my invention, what I desire to claim, andsecure by Letters Patent, is

The method of forming a satchel'bottom on a paper tube having inwardbellows-folds, which consists in cutting apart the corners A A A A, thenspreading open one end of the tube so as to form the inward projectingpieces 0 O, flaps D D, and pieces F and G, which flaps D D and pieces Fand G are fastened together by paste or other suitable material,substantially as shown and described.
